The inner escutcheon 500 is a member that not only houses the display device but also plays a role of decoration and electronic device protection in a state where the display device is tilted.

  Output signals for the display device are transmitted from various internal units housed in the casing of the navigation device 1. For example, video information to be displayed on the display device is transmitted from the second internal unit 300 or the like. An input signal for transmitting input information received by an input detection device (for example, a touch panel) provided in the display device is transmitted to various internal units housed in the casing of the navigation device 1. Such input / output signals need to be transmitted and received stably even during the tilt operation in order for the display device to perform the tilt operation. Therefore, in the navigation apparatus 1 according to the present embodiment, the signal is transmitted and received through the flexible printed cable 350. However, the flexible printed cable 350 has a length necessary to secure a certain range of movement in consideration of the tilting operation of the display device, and is not loose so as not to cause unnecessary entanglement. It is necessary to suppress. In order to suppress this bumping, it was necessary to work with a dedicated jig.

  In the embodiment of the present invention, the device connected to the display device via the flexible printed cable 350 is an arithmetic processing unit including an audio board and a navigation board assembled to the second internal unit 300. That is, it can be said that the navigation device 1 includes the flexible printed cable 350 that connects the device disposed inside the housing and the device disposed outside the housing across the inner escutcheon 500.

  The flexible printed cable 350 is connected from the second internal unit 300 to a display device outside the housing through a gap 510 (see FIG. 4) provided in the inner escutcheon 500. In the gap 510, an FPC cover 360 is provided, and the degree of freedom with respect to the position and length of the flexible printed cable 350 is limited. The FPC cover 360 and the flexible printed cable 350 are fixed to the inner escutcheon 500 by a left screw 370L and a right screw 370R.

  4 and 5 are perspective views showing the state of the navigation device 100 before the FPC cover 360 is attached. The flexible printed cable 350 is attached by being folded into a predetermined shape. Further, a right screw hole 361R and a left screw hole 361L are provided at two positions on the left and right ends of the FPC cover 360. A left temporary fixing hole 350L and a right temporary fixing hole 350R are provided at both ends of the flexible printed cable 350 in the short side direction at predetermined positions. The inner escutcheon 500 has a right screw hole 371R, a right temporary fixing hole 380R, a left screw hole 371L (not shown), and a left temporary fixing hole 380L (not shown) corresponding to the right screw hole 371R and the right temporary fixing hole 380R, respectively. Is provided. Here, a right screw 370R that passes through the right screw hole 361R of the FPC cover 360 is screwed into the right screw hole 371R. Further, the left screw 370L is screwed into the left screw hole 371L through the left screw hole 361L of the FPC cover 360.

  FIG. 6 is a perspective view of the FPC cover 360 as viewed from the side attached to the inner escutcheon 500. The FPC cover 360 is made of resin or the like. The FPC cover 360 is provided with a right screw hole 361R and a left screw hole 361L. The FPC cover 360 is provided with a right cable fixing protrusion 362R and a left cable fixing protrusion 362L. The right cable fixing protrusion 362R and the left cable fixing protrusion 362L pass through the right temporary fixing hole 350R and the left temporary fixing hole 350L of the flexible printed cable 350, respectively, and are inserted into predetermined holes provided in the inner escutcheon 500. Accordingly, the flexible printed cable 350 is positioned with respect to the inner escutcheon 500 and temporarily fixed.

  The FPC cover 360 further includes a right positioning protrusion 363R near the right end center, an upper right positioning protrusion 363TR near the upper right end, a left upper positioning protrusion 363TL near the upper left end, and a left positioning protrusion near the left end center. 363L is provided. Each protrusion is fitted into a positioning hole provided at a corresponding position of the inner escutcheon 500. That is, the right cable fixing protrusion 362R, the left cable fixing protrusion 362L, the right positioning protrusion 363R, the upper right positioning protrusion 363TR, the left upper positioning protrusion 363TL, and the left positioning protrusion 363L are fitted in the corresponding holes of the inner escutcheon 500, respectively. The flexible printed cable 350 is positioned and temporarily held at a predetermined position without screwing with the right screw 370R and the left screw 370L. As described above, the flexible printed cable 350 has a length and the like necessary to ensure a certain range of movement, and can be attached with reduced bumping so as not to cause unnecessary entanglement.

  The above is the first embodiment according to the present invention. According to the embodiment, the navigation device 1 can temporarily hold the component without using a special jig. Therefore, the amount of work required for assembly can be reduced while improving the assembly accuracy of the navigation device. Also, if there is a mistake in assembly, it is easy to correct the mistake and reassemble. This is because screwing is performed last, and therefore, in the temporarily held state up to that point, it is possible to reassemble the internal units without removing the screws.

  According to the above-described embodiment, the flexible printed cable 350, which is a transmission path that connects the internal electronic component and the display device, is easily positioned and positioned by accurately positioning while maintaining flexibility. It is done. In addition, since the holding force is continued after the attachment, the display device is stable even when the tilting operation of the display device is repeated.

  The present invention is not limited to the above embodiment. The above embodiment can be variously modified within the scope of the technical idea of the present invention. For example, in the above embodiment, the metal casing 100 has a U-shape and includes a top surface and left and right side surfaces, but is not limited thereto, and includes, for example, left and right side surfaces and a bottom surface. It may be provided with only the top surface or only the bottom surface. By doing in this way, also about the navigation apparatus provided with frame | skeleton of various shapes, temporary holding can be performed and a screwing process can be integrated now in a downstream process.

  Further, for example, in the above embodiment, the flexible printed cable 350 extends from the front of the navigation device 1 to the outside. However, the present invention is not limited to this, and may extend outward from the side surface, the back surface, or other surfaces. Further, the flexible printed cable 350 is not limited to a signal line connected to the display device, and may be a signal line or the like when a device for receiving an operation of the navigation device 1 is connected by wire.

  In the above, this invention was demonstrated centering on embodiment. In the above-described embodiment, the example in which the present invention is applied to the navigation apparatus has been described. However, the present invention is not limited to the navigation apparatus and can be applied to all apparatuses having an assembly structure.
